BAG SEAL Filed March 15, 1946 Patented Mar. 6, 1951 UNITED STATES PATENT OFFICE 9 Claims.

The present invention relates to bag seals, and has for its main object the provision of a casing composed of two interlocked sections, and within which casing a knot of a cord encompassing the neck of a bag, is enclosed.

A still further object of the present invention is the provision of a seal of the character indicated, with cooperating means for preventing the cord loops encompassing the neck of the bag from being disengaged therefrom by sliding the loop longitudinally of the neck of a bag.

A still further object of the present invention is the provision of a seal of the character indicated wherein the knot of a cord encompassing the neck of the bag is enclosed, the loop of which cord is passed through an eye of a pin, the latter pierced through the neck of a bag and engaged with the seal, for the purpose of preventing the cord loop from being disengaged from the neck of a bag.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

Referring in detail to the present drawing the,

ultimate seal I2 embodies a pair of sections or parts I3 and M, which, when interlocked, define the casing of seal l2. a common, oblong, bottom wall I5, the ends of which are of arcuate formation. integrally formed with said bottom wall I5 is a side wall cooperating with each of said parts I3 and I4.

Said side wall includes straight parallel portions,

I6 connected with arcuate portions IT in each of said parts I3 and I4. Bottom wall I5 cooperating with part I3 is wider than the end thereof cooperating with part It for the purposes hereinafter stated. Wall portions I6 of each part I3 and I4 are spaced, effecting recess I8, with the resultant free, central bridge I9 in said bottom wall I5, which said bridge I9 in the ultimate formation of seal I2, when parts I3 and I4 are interlocked, will constitute one end wall in said seal I2.

Said bridge I9 adjacent part I3, and in a transverse relation with said bottom wall I5 is provided with a row of four apertures 20 and with aperture 2| adjacent part I l and centrally of said bridge I9 at the opposite side thereof, for the purpose hereinafter specified.

Each straight wall portion I6 of part I3 is doubled upon itself as at 22, down to bottom wall I5, and bent at its lower termination, and adjacent said bottom wall I5, as at 23, and from that point directed upwardly in a slanting direction for effecting leaf 24, and thereupon bent toward doubled portion 22 for effecting comparatively short lip 25, which overhangs V-shaped recess 26 resulting from said doubled up portion 22 of wall portion It, and leaf 24.

Each of straight wallportion I5 of part It of the seal are inwardly bent with the resulting depending leaf 2'5, the free ends of whichare spaced away from bottom wall I5, as is clearly seen in Fig. 4.. Each side wall portion I6 of part I4 is inclined towards the longitudinal center of Said parts I3 and I4 have part I4, and each cooperating leaf 2! is directed in a perpendicular manner with respect to bottom wall I5, so that wall portions I with their cooperating leaves 21 define V-shaped recesses 28, the apex of each of which coincides with the free ends of said wall portions I6, and' the wider ends of which are adjacent said bottom wall I5.

Along the base of each side wall portion I6 of part I4, adjacent bottom wall I5 each of said side wall portions I6 is inwardly bent for defining grooves 29 coextensive with the length of said side wall portions it, for the purpose hereinafter stated.

Bridge I9 along its sides, and adjacent parts I3 and I4 is creased as at 30 for facilitating bending bottom wall [5 along said creases 30 so that in the ultimate formation of seal I2 saidcreases 3!] will constitute corner points from which'bridge I9 and the adjacent ends of bottom wall I5 will extend in a perpendicular mutual relation, and the two ends of bottom wall I5 will remain in parallel relation and will then define faces 3I of seal I2.

When said parts I3 and I4 are shifted towards each other when bottom wall I 5 is bent along creases 30 as aforesaid, the apexes defined by side wall portions IS and their depending leaves 21 will enter recesses 26 of part.I3 and further forcing of part I4 into 'part I3 will shift said last named side wall portions I6 and their leaves 21 downwardly within recesses 26 of part I3, during which shifting process leaves24 with lips 25 are deflectedaway from doubled up wall. portions 22, until said 'apexes reach angles 23 de-- fined by said doubled up wall portions 22 and leaves 24. When in that position leaves 24 with their .lips 25 will spring back into their normal position, with lips 25 overhanging the free ends of leaves 2'! and in alinement with the inner faces of the latter, by virtue of which action said lips 25 will straddle the free ends of said leaves 21, thereby interlocking part I4 of seal I2 with part I3 thereof, preventing disengagement of the two parts of the seal, unless the seal is damaged or destroyed. When the two parts of seal I2 are interlocked, as is seen in Fig. 5, the free ends of said wall portions I6 with their doubled up Walls 22 will repose within grooves 29. Since end of bottom wall I5 of part I3 is wider than the corresponding end of said wall I5 adjacent part I4, there is no difficulty of accommodating the interlocking parts of said wall portions IS of said part I4 with the corresponding interlocking parts of said part I3 of the wall, as is seen in Fig. 5. It is further observed that the arc of end wall portion I! of part I3 is of a larger diameter than the corresponding arc of end wall portion I! of part I4, so that when the two parts are in an interlocked condition, defining the seal casing, the-arcuate end wall ll of part I4 reposes within the arcuate endwall I! of part I3 and contacts its inner periphery.

The seal is made preferably out of metallic resilient material or of plastic so that leave 24 are capable of-being deflected away from the doubled up walls 22 during the shifting .of side wall portions I6 with leaf 21, and being capable of springing back into the original position for causing lips 25 to enter recesses 28 when overhanging the free ends ofleaves 2'1. For permitting clearance for said lips 25 when they spring into ultimate operative position past leaves 2'! the latter are spaced away from their cooperating bottom wall I 5.

From the hereinabove description it will be seen that once said parts I3 and I4 are interlocked for forming the casing of seal I 2, it is impossible to have access into the interior thereof, without destroying, disfiguring or damaging seal I2. Thus the cord knot reposing within seal I2 cannot be untied unless seal I2 is either broken or the strand of the cord remaining outside of the seal is cut.

The seal herein disclosed is intended for use in connection with containers, such as fabric bag 32, adapted to receive valuables, with the open end of the bag formed into a constricted neck 33.

After the contents have been deposited into bag 32 with the open end thereof folded into compact neck 33, double loops 34 of cord 35 are encompassed around neck 33. Said double loop 34 is made by passing free ends of cord 35 through a pair of outermost apertures 20, then the ends thereof are passed through eye 36 of pin 3'! and there crossed, as is seen in Fig. 9, and thereupon said ends areextended through the innermost apertures 29, as is seen in Fig.8. When loop 34 is preformed as hereinabcve stated, and as shown in Fig. 8, a portion of a bight of one strand of said loop 34 Will face or overlie the inner face of bridge I9, as at 38, with the remaining portions of double loop 34 remaining around neck 33 and outwardly of the outer face of bridge I9. When double loop 34 is preformed, as shownin Fig. 8, withtwo free ends of cord 34 passed through the innermost apertures 20, and with the two strands of loop 34 passed through eye 33 and there crossed, thereupon pin 3'! is driven into and pierced transversely of neck 33 and in a substantially diametrical relation therewith. Flattened outer portion of eye 36 defines head 39 which facilitates the application of manual pressure thereat for driving pin 31 through said neck 33. When said pin 31 has entirely pierced neck 33, the free sharp point thereof is inserted into aperture 2| and shifted outwardly of bridge I9 as far as it will go. During this operation bridge I9 by its outer face is contacted with neck 33. Pin 31, remaining within aperture 2I will frictionally support said bridge I9 as well as parts I3 and I4, and thereupon free ends of cord 35 are pulled to eliminate any slack in double loop 34, and thereupon said free ends of cord'35 are tied into knot 40 shown in dotted lines in 'Fig. 7. When this is accomplished the two-parts I3- and I4 are bentalong creases 30' for interlocking the same as hereinabove described andfor providing closed seal I2. From the hereinabove description it will be seen that the inner free end of pin 31 when inan ultimate operative position with respect to seal I2, remains within said seal I2, as is indicated by dotted lines in Fig. '7, being extended thereinto through said aperture 2I made in bridge I9. Said seal I2 in its ultimate interlocked condition contacts with the adjacent point in the periphery of neck 33, as is seen in Figs. 6 and 7.

From the hereinabove description it will be apparent that once two parts I3 and I4 of the seal have been interlocked, no access may be had to knot 40 within seal I2 for untying the same or for tampering therewith. It will also be seen that pin 3'! when pierced through neck 33 with its free sharp end remaining within seal I2 cannot be removed from said neck 33, because double loop 34 maintains it in that operative position due to the engagement of loop 34 with eye 36. Thus, when said pin 3'! is pierced through neck 33 with loop 34 in a tight condition therearound, pin 31 cannot be shifted transversely in either direction, because eye 35 does not permit itshiftin towards seal l2, and loop 34, in engagement with eye 36, does not permit it to shift into the opposite direction.

From the 'hereinabove description it will also be seen that loop 34 cannot beshifted along neck 33 and longitudinally thereof, because such shifting is prevented by said loop 34 being in engagement with eye 36,

Therefore the only wa that access may be had into bag 32 is tobreak cord 35 along one or both strands of loop 34. A person without authority doin this would of course be charged with breaking the cord. There is no way of effecting access into bag 32 through tampering with seal 12 in an attempt to open the same, because once two parts l3 and M are interlocked, the same may not be opened short of breaking or destroying the same.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be madetherein without departing from the spirit and scope of the invention as claimed.
